I've been looking at booking a trip to BKK for the last 2 weeks of April for some time now but I keep getting sticker shock. Going in Tango and return in Tango Plus is coming in at about $2,500 on the AC website. Travelocity and Expedia have Tango Fares at just over $1,600. Why are the prices so high now? It was like $1,200 in Tango Plus last year.
